The 4CsBeautiful. Cherished. Desired. Unique. Each diamond is a miracle of time, place and geological circumstances. While the emotional value of diamond jewellery is immeasurable, its physical characteristics combine to establish its monetary value. Until the mid-twentieth century, there was no consistent standard by which diamonds could be graded. In the 1940’s The Gemological Institute of America, (GIA) created the first, now globally accepted, standard for describing diamonds by means of: Colour, Clarity, Cut and Carat Weight. The creation of the Diamond 4C’s allowed for two essential changes within the industry: Diamond quality could now be measured on a universal scale, and the history of each diamond was documented and made accessible. Today, the GIA is firmly established as the global authority on diamond evaluation and their GIA International Diamond Grading System™ is the universal method for assessing the quality of any diamond, anywhere in the world. Mindham Fine Jewellery prides itself on sourcing the finest of stones, including GIA certified diamonds. Please visit our showroom at 37 Hazelton Avenue to see our collection of fine jewellery, including pieces with GIA certified diamonds, or to discuss a custom creation.
CaratDiamond weight is measured in “carats”. 1 carat weights 0.20 grams. A carat is broken into 100 points, so, for example, a 0.50 carat diamond is referred to as a half-carat diamond
ClarityAs natural stones, all but the rarest of diamonds contain imperfections, referred to as “inclusions”. Depending on their size, number and location, these can obstruct the flow of light and decrease the clarity. Diamonds are examined under 10x magnification and graded ranging from FL (Flawless) to I-3 (Heavily Included)
